Abstract: ABSTRACT OF THE DISCLOSURE A terrestrial magnetism responsive device adapted to be worked using a north or south seeking magnet in both north and south headings, the device including a housing having a north or south seeking magnet therein, The magnet is suspended adjacent one pole by a sensitive spring to permit the magnet to be movable horizontally, when released, from a north pointing position or a south pointing position. Secured and balanced on the seeking or free end of the magnet is a soft iron rod, generally at ninety degrees to the magnet and having substantially the same diameter as the magnet. The rod is balanced along with the magnet so that the magnet and rod together will move horizontally. The housing is rotatable on a plate by which it is held and during operation is fixed on the plate to be moved horizontally in the direction of an area to be explored. The method includes the releasing of a north or south seeking magnet in the housing so that it is free to move east and west on the spring as the housing in its fixed directional position is moved over the areas to be explored. As it is moved, the east/west diversions of the magnet and the exact locations of the diversions are recorded to be used in deter-mining the location of surface and subsurface local structures which have local magnetic force fields causing the diversions of the magnet,

Abstract: THREE-WAY HANDLE-OPERATED WALL-AVOIDING RECLINER CHAIR        ABSTRACT OF DISCLOSURE         A three-way, handle-operated, wall-avoiding, recliner chair with dual footrests.  From closed position, the chair is operated to TV position by means of a handle connected to the footrest mechan-ism. The handle is also connected to a rear seat mounting link to move the seat forwardly relative to the base during which time a restraining mechanism prevents the backrest from moving relative to the seat.  Once in the TV position, the restraining mechanism is no longer effective, and the occupant may exert pressure on the backrest to recline the seat further relative to the base while also moving the backrest forwardly relative to the seat as well as the base to avoid striking any nearby wall.  Novel linkage mechanisms are provided for carrying out the above, and a spring mechanism is provided to lock the footrest closed against inadvertent actuation such as when the chair is being relocated and is being pulled by its armrests.

Abstract: Abstract An injection assembly includes a packer set in the casing adjacent to the producing zone, having a bore sized to receive production tubing.  A portion of the assembly suspended from the string of production tubing includes a side pocket mandrel, a twin flow head, an extensible telescoping housing, and coacting joint means on the extensible housing and the packer for axial joining of these members.  The side pocket mandrel, twin flow head, and twin flow converter provide a first passage joined to the production tubing; and a length of inner tubing joined to the twin flow converter extends this passage down into the bore of the packer.  These members provide a second passage beginning at the side pocket mandrel and open-ing to the annulus between the casing and the string of produc-tion tubing, and extending downward to the packer through the annulus between the inner tubing and the surrounding structure, which surrounding structure includes the outer housing of the twin flow converter, the extensible housing, the joint, and the packer mandrel.  After joining to the packer the upper por-tion of the assembly is raised to extend the extensible housing and to raise the lower end of the inner tubing from its lower limiting position within the packer.  An injection method, which may be practiced with the above described assembly, is also des-cribed.

Abstract: ABSTRACT OF THE DISCLOSURE      A method for increasing the ability of apoglucose oxidase to combine with flavin adenine dinucleotide (FAD) and derivatives thereof to form active glucose oxidase by interacting apoglucose oxidase with an immunologically derived binding substance, e.g., an antibody or a fragment thereof, having a specific bind-ing affinity for glucose oxidase.  The apoglucose oxidase/anti-glucose oxidase immune complex is characterized by enhanced ability to combine with FAD and FAD-derivatives to yield glucose oxidase activity. The activation is particularly significant at tempera-tures elevated from room temperature, e.g., between 30°-45°C.  An improved homogeneous specific binding assay method is provided for determining ligands wherein an FAD label is used and is monitored by its ability to combine with apoglucose oxidase to form active glucose oxidase by including anti-glucose oxidase in the reaction mixture.

Abstract: ABSTRACT A process for the conversion of ground hydrous lignite into a pumpable dehydrated suspension of fine ground lignite and oil is provided which process comprises mixing ground hydrous lignite with oil of a higher boiling point and with a lower boiling hydrocarbon or hydrocarbon fraction to form a pumpable suspension, grinding the lignite in the suspension in a grain size of less than 2 mm., subjecting the suspension to a pressure of 30 to 80 bar and heating it to a temperature of 190 to 240 °C, maintaining the suspension under these conditions for at least 5 minutes, separating the suspension into a partially dehydrated lignite and oil slurry and a water, hydrocarbon and oil liquid, mixing the lignite and oil slurry with an oily phase obtained from separation of the water, hydrocarbon and oil and depressurizing the lignite and oil slurry to 1 to 18 bar at a temperature of 190 to 240 °C so as to obtain a dehydrated lignite and oil suspension and a water and hydrocarbon fraction. The process of the present invention overcomes the expense as regards energy and equipment and the influence on the thermal efficiency of the hydrogenation process associated with known methods of dehydration by evaporation, and obviates the need for large heat exchangers as is required with the removal of water by distillation.  Moreover, the hydrous lignite and oil sludge exhibits good flowability.

Abstract: RECEIVER GARMENT FOR WEAPONS ENGAGEMENT            SIMULATION SYSTEM      ABSTRACT A weapons engagement simulation system includes a weapon simulator having a laser transmitter for transmitting pulses of directed coherent light in a characteristic temporal pattern and a receiver garment. A plurality of photosensitive detectors distributed over each of a plurality of discrete zones on the outside of the garment respond to light from the laser transmitter by producing electrical detection pulses systematically related thereto.  Comparators compare the electrical detection pulses from the photosensitive detectors in a respective zone with a predetermined threshold level and produce discriminated detection pulses when said electrical detection pulses are greater than the threshold level.  A decoder compares the temporal patterns of the discriminated detection pulses with a temporal pattern characteristic of the laser transmitter and produces a hit signal corresponding to a respective corresponding zone when the compared patterns correspond.  Visual indicators disposed in respective ones provide visual signals when actuated by the respective hit signals.  Priority is given to hits in accordance with predetermined priority given respective zones.
